I think this is an excellent questions that should be splitted into questions per type of tool (databases, processing, catalog software) so the conversation remain focused.

I've compiled a fairly extensive list of open government portals both in US and around the world in the last few days. I am working on code to support crowdsourcing the catalog. I also have a CSV version for download. There is about 700 sites listed so far:

Civic Dynamics- CDP is a proven, open-source turnkey software platform for managing and publishing open, community data. It is used for local government data and community indicator systems. It enables the publishing of open data in a dynamic format that allows citizens to easily view, mix, match and download data for analysis, as well as contribute their own information and thoughts - thereby facilitating true citizen engagement. Given these attributes, it is recommended that CDP would fit under two of the identified categories:

Kelly, so that people are well-informed, we ask that people disclose in each message when they have a relationship w/ a project or company that they're mentioning. (see opendata.stackexchange.com/help/behavior , under 'self-promotion'). You've done it in your user profile, but we ask that people put it specifically in their answers that may have a conflict of interest.

Exversion is open data infrastructure. It allows people to create data repositories same way they might create code repositories on github (for example) and share this data with everybody or with a select group of individuals. Any additions or changes made to the data are recorded in the version history, can be rolled back and data repos can copied into new branches to produce different versions of the same information. Like I said, work in progress but that's the general idea :)

Can you expand this so it's more understandable?

It's not clear to me that Exversion qualifies as an open data system, but maybe if you expanded per Jeanne's recommendation you could explain that to us.
